The Wonderboom 4 is Ultimate Ears’ latest ultra-portable pool-friendly speaker, and it sounds far better than you’d think, given its modest size. In our early tests, the Wonderboom 4 has deeper bass and clearer midrange performance than any speaker we’ve tested in its held-in-the-palm-of-our-hand size class. We’re also fans of its design, from the mesh covering made partially out of recycled plastic to the giant volume buttons that are easy to press and impossible to miss. Ultimate Ears says the Wonderboom 4 lasts up to 14 hours per charge, and its IP67 rating means it can be fully submerged underwater without being permanently damaged. Though it probably won’t be because it floats. Don’t skip this deal if you need an ultra-portable speaker that can still pack a punch.
